Born as Lucius Septimius Bassianus (188-217 CE) but renamed Marcus Aurelius Antoninus after his father's union with the families of the Nerva-Antonine dynasty; he gained his agnomen Caracalla from a Gallic hooded tunic which he often wore. Eldest son of Emperor Septimius Severus; he reigned jointly with his father from 198 CE until his father's death in 211 CE. He then became joint emperor with his younger brother Geta; but he quickly murdered his brother less than a year into their joint rule.

Caracalla's reign was marked by continued assaults from the Germanic peoples as well as constant domestic instability. Caracalla was famed for enacting the Edict of Caracalla; also known as the Antonine Constitution; which granted Roman citizenship to almost all the freemen living throughout the Empire. He was also known for his establishment of a new Roman currency; the antoninianus; as well as building the Baths of Caracalla; the second largest in Rome. In terms of infamy; Caracalla was known for his massacres against the Roman people and other citizens of the Empire.

Caracalla's reign ended in 217 CE; after he had instigated a new campaign against the Parthian Empire. Caracalla had stopped briefly to urinate when a soldier approached him and stabbed him to death; incensed by Caracalla's refusal to grant him the position of Centurion. Caracalla would be posthumously known for his savage cruelty and treachery; as well as for murdering his own brother and his brother's supporters.
